• Varying materials of construction to meet your chemical resistance needs and ATEX compliance
  • Three materials of construction offer a solution to meet your budget
  • Head design greatly reduces dead space to provide superior vacuum performance
  • Oil-free pumps keep your pumped medium clean

We offer an extensive range of head/diaphragm wetted parts—from PVDF-coated aluminum, solid PTFE, 316 stainless steel, to aluminum and nitrile (available online). The PTFE heads are constructed of solid PTFE resin. The molded diaphragm has a thick PTFE-resin coating to provide the best resistance available to the toughest corrosive vapors. The stainless steel heads are machined from wrought 316 stainless steel, resulting in surfaces that are smooth, leaktight and free of occlusions.

The single-head pumps offer moderate flow and vacuum or pressure performance. The pumps with twin heads in parallel offer higher flow for your sampling requirements.
